RED/SWOLLEN/SORE palms of hands - dry mouth

[jeblondon]

Hi, I have just returned from holiday and am in a mess! I try to aoid wheat and gluten where possible (I have never been diagnosed as definite Coeliac but have all the symptoms) but on this holiday I blew it. It was a speial celebration and so I ate whatever I fancied. I had muesli every day with yoghurt plus bread with my meals etc. I got the bloating and gas problems back and some joint pains but 2 days ago the palms of my hands turned a blotchy bright red and felt as if they had literally been 'burned'. Very painful! I am home now and the skin on my hands feels like it is too tight - painful to make a fist and still very red and blotchy. My mouth feels very dry all the time. While on holiday I was also eating more dairy than normal and lots of exotic fruits like papaya and pineapple - which I have heard can also cause allergic reactions.
I seem to be getting more and more allergies to things as I get older - why? I have Positive ANA and have been told I have definitly got 'some kind of immune disorder' but they don't know what!!!
I am 49 and have just started taking HRT one month ago. I also take 25mgs thyroxine daily for underactive thyroid/hashimotos. ANY ideas or suggestions would be fantastic as I am completely baffled with this strange reaction. I see my Doctor on Tuesday and will take any responses into consideration.
Kind regards as always.
